Car & Driver is
reporting the rumored BMW
M4 GTS will be revealed this August.

BMW recently took the wraps off the 2015
M4 Coupe MotoGP safety car and it's currently on display at the Geneva
Motor Show featuring a water injection system. The Bavarian marque has already
hinted the new hardware will be implemented in a future production model and it
seems the car in question is the M4
GTS which has been already spied several times by our agile photographers.

The car will apparently be revealed in conceptual form this August
at Pebble Beach and aside from the water injection system it could also boast
laser headlights and OLED taillights if we were to believe a report
issued by Spanish media last month.

Expect the M4 GTS to feature more carbon fiber and aluminum
components to shave off weight compared to the regular model which tips the
scales at 1,572 kg (3,465 lbs). Moreover, the water injection system will help
boost output of the six-cylinder 3.0-liter TwinPower Turbo engine beyond the
current 431 HP (317 kW) and 550 Nm (406 lb-ft). Other upgrades on the menu include stickier tires, stiffer
suspension, beefier brakes and also a minimal interior trim to cut kilos even
further.
